My  hardware store, and I bet any in Minnesota, has a pretty big
selection of them.
They cost about a buck a piece.  The ones I've been using have a pair
of groves cut in them, about a 1/16 thick.  Neither the original ones
(which are pins, held with cotter key) or the replacements, which are
threaded, have any grade makrings on them.
